This is now being cross-posted to comp.emacs. I first posted this query in the Kermit
newsgroup. They are indicating that it is an Emacs issue -- one that changed since an
earlier version. I am using version "21.2.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll
bars) of 2002-08-28 on astest" on Red Hat 8.0 with current updates.
